As you can see from the jquery.ui.datepicker.js coding shown below, I have managed to successfully set the minDate to 1 and maxDate to 60days but if on line 92, I replace null with $.datepicker.noWeekends, the drop down calender will not appear on the form

89 minDate: 1, // The earliest selectable date, or null for no limit
90 maxDate: 60, // The latest selectable date, or null for no limit
91 duration: '_default', // Duration of display/closure
92 beforeShowDay: null, // Function that takes a date and returns an array with
93 // [0] = true if selectable, false if not, [1] = custom CSS class name(s) or '',
94 // [2] = cell title (optional), e.g. $.datepicker.noWeekends
The web form can be found here: http://www.skipy.co.uk/skip_online_order_form.html#top
I'm really puzzled as to why it won't work and would appreciate any advice.
